OF NEVIT YORK, N. Y.

IMPROVEMENT IN HOLLOW-TILE WALLS.

Specification forming part of Letters Patent No. 112,925, dated March 21, 1871. i

To whom it may concern.:

Bc it known that I, GEORGE H. JOHNSON,

ofthe city, county, and State ot' New York, have invented a new and useful Improvement in Hollow-Tile Walls 5 and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanyin g drawing, forming part ofthis specification, in which drawing- Figure 1 represents a perspective view of this invention. Fig. 2 is a longitudinal vertical section of the same, the line x w, Fig. 1, Fig. 3 is a transverse section of the same, taken in the plane indicated by theline y y, Fig. 1.

Similar letters'indicate corresponding parts.

This invention relates to a wall which is constructed of hollow tiles, each provided with one or more air-channels and with one or more lips, in such a manner that when the tiles are put together the lips of the runners (or tiles put down with their long sides in the direction ofthe front of the wall) will catchinto the air-channels ot' two runners below, while the.

lips, of the binders (or tiles placed in a transverse direction) catch in the spaces left between tlie runners below, and by these nica-ns awall is obtained which is very firm, and

which allows of a free circulation of theair.

ln the drawing, the letter A designates a wall, which is composed of runners B and binders C. rlhe runners are constructed each with one air-channel, c, and with two lugs or lips, b, projecting from their ends in a downward direction, (best seen in Fig. 2,) while the binders are provided each with two air-chanunels, c, which are separated from each other by a partition, d, (see Fig. 3,) and from the -bottom edge of this partition projects a lip, e. In building a wall with these tiles, I place two runners, B, side by side, leaving an intermediate space, f, and across their ends I placetween the runners B B of the first layer. Thel third layer is arranged precisely like the iirst, and the fourth like the second, and so on.

By these means a wall is obtained which is very rm in every direction, and which, on account of the free circulation ofthe air through the several air-channels, is dry and warm; and, furthermore, a wall constructed according to my invention is comparatively light, so that no extraordinaryfoundation is required to support a building ot great strength and durability.

My wall can be put up by ordinary labor, since the work cannot be got out of perpendicular, and it can be erected in winter or in wet weather, since itirea'dily dries. Hot or cold air may be forcedlthrough it for heating and Ventilating thc building.

My wall is also ot' great adyal'ltage for partitions in the interior part of a building, sinccv it is light, and, at the same time, tire-prooi".

What I claim as new, and desire to secure by Letters Patent, is-

A wall composed ofthe runners B, with ar channels c and lugs b, in combination with the binders O, having air-channels c and lugs c, said runners'and .binders being arranged in relation to each other substantially as dcscribed, for the purpose specified.
